this movement is transmitted to the standard l5

proper vertical adjustment of the shaft. By ar

What I claim is:
1. In a bearing adjuster, a block, a bearing
85 standard slidable in said block, a screw in said
block, the inner end of said screw tapered and
engageable with a surface of saidstandard, where
by movement of the screw will be transmitted to
said standard, a locking plug in said block adapted
40 to engage a side of said screw, and a locking
screw in said block parallel with said ?rst men
tioned screw, said locking screw having an in
clined inner end to engage and move said plug.
2. In a bearing adjuster, a frame, a block, a
bolt in said frame engaged in said block, said
block having an opening therein, a standard
slidable in said opening, a screw in said block
having a tapered inner end, said end projecting
into said opening and in engagement with the
lower end of said standard, said block having a
passage communicating with one side of said
screw, a locking screw in said block in spaced
parallel relation with said ?rst mentioned screw
and having a tapered inner end, a plug slidable in
said passage, the tapered end of said locking screw
engaged behind said plug, whereby movement of
said locking screw in one direction will move said
plug into engagement with said ?rst named
3. In a bearing adjuster, a block having an 15
opening, a bearing standard in said opening, a
screw disposed axially in the lower end of said
standard, a beveled head on said screw, said block
having a lateral opening disposed at substantially
right angles to said standard and communicating
with the lower end of the opening therefor, and
"1e inner end of said screw being tapered and en
gaged with the beveled head on said ?rst named
4. In a bearing adjuster, a support, a bearing 25
slidable in said support, an adjusting screw in said
support for moving said bearing, a locking plug
in said support for engagement with said adjust
ing screw, and a locking screw in said support in
spaced parallel relation to said adjusting screw 30
for moving said plug into engagement with said
adjusting screw.
5. In a bearing adjuster, a bearing support, a
standard slidable longitudinally in said support, a
bearing on said standard, an adjusting member in 35
said support disposed parallel with said bearing
and adapted to move said standard, a locking plug
in said support adapted to engage and lock said
adjusting member, and an operating element in
said support disposed parallel with said adjusting 40
member for moving said plug.
